Quality inspection

We deliver different types of reports depending on your needs. A graphical report with color plot shows at a glance the deviations between scan and CAD model. Additionally, we offer technical drawing checks (with numbered dimensions for clarity), GD&T analyses such as flatness and profile tolerances, and spreadsheet reports that combine measurements from multiple cavities or production runs. We can also fill in your own template if you wish.

Absolutely. We always start with the right questions: why do you want this scanned? What is the problem in your production? Sometimes a customer requests hundreds of dimensions, but after further inquiry we discover that a well-chosen color plot in a specific alignment, whether or not across a series of samples, reveals the problem much more effectively. Our customers sometimes think too much in 2D, while we truly think in 3D. By working closely together, we deliver the greatest value: you are the expert in your production process, we are experts in extracting the right 3D information.

An actual-to-nominal comparison (also called a color plot) visually shows the difference between the scanned part and the nominal CAD model. Deviations are displayed in color, so you can see at a glance where the produced part deviates from the design. This is particularly popular in the injection molding world, where small process changes can have a major impact on the end result.

GD&T (Geometric Dimensioning and Tolerancing) is an international system for specifying tolerances on form, position, and orientation of features. We perform complete GD&T analyses, including flatness, profile tolerances, position tolerances, and more. The visualization in our reports clarifies exactly where the reported values come from, so you can adjust your process in a targeted manner.

Yes. With both optical 3D scanning and CT scanning, we can scan multiple parts simultaneously. This makes series measurements cost and time efficient. Think of golden samples, pre-production inspection, SPC measurements (Statistical Process Control), and final inspections. Our spreadsheet reports combine measurements from multiple cavities and production runs in one clear document.

A First Article Inspection is a comprehensive dimensional check of the first produced part from a new production process or mold. All dimensions from the technical drawing are measured and reported. This provides assurance that the production process is set up correctly before series production starts. We consistently number all dimensions throughout the project for maximum clarity.

In addition to the reports, we provide a free ZEISS Inspect viewer file with each project. Our customers sometimes think too much in 2D, while the power of our data lies precisely in 3D. That’s why we encourage you to also look at the results in 3D yourself. A web meeting where we operate the software live works best to go through everything together.

The applications are broad. Common analyses include golden master controls, sections, curve-based analyses, shrinkage analyses, gap and flush analyses, digital assemblies, and springback analyses. This is relevant for sectors such as injection molding, automotive, healthcare, packaging industry, and additive manufacturing.

With optical 3D scanning, we inspect the external geometry of the part based on structured or laser light. With CT scanning, we also map the internal structure, which is essential for porosity analyses, internal defects, and assembly inspections.

Yes. TetraVision holds an ISO 17025 accreditation, granted by BELAC. This guarantees that our measurement results are reliable, accurate, and traceable. ISO 17025 specifically assesses the technical competence of our laboratory, including validated measurement methods and calculated measurement uncertainties.

Our standard lead time is approximately 5 working days. The exact delivery time depends on the complexity of the reporting and the number of dimensions to be checked. Contact us for a concrete estimate, we always respond within 24 hours.

The price depends on the type of analysis, the number of dimensions, the number of parts, and the desired report format. We create a customized quote for each project. Request your quote here, you will receive it within 24 hours.
